No, what I did do is instead of using a second animation on the same audio file in the beginning and end I added a second copy of the same audio file and placed that one's timing at the end and for some reason the video saved. this may not work in every instance. I don't get this error message often but when I do it usually means a complete rebuild of my presentation to get it to save to video.

Now I'm having another problem unrelated to Microsoft, when I save the video to my Android phone there's a 3 second sound bite in it that's garbled, and only that 3 second segment, however it plays fine in Windows. First time I've ever experienced this problem so I'll have to find an Android forum for this one. Android phones automatically convert the file type from MP4 to some other format when saving to the phone. Thank you.
